Dams can cause several types of pollution, primarily through the alteration of water quality and ecosystem disruption. They can lead to nutrient loading, which promotes algal blooms, and the accumulation of harmful substances like heavy metals and pesticides in stagnant water. Additionally, the decomposition of organic material in reservoirs can produce methane, a potent greenhouse gas. The alteration of natural water flow can also impact sediment transport, affecting aquatic habitats and water quality downstream.
